Fumigant for wood parasitic nematodes and wood fumigation method

Abstract

The present invention provides a fumigant for wood parasitic nematodes comprising methyl iodide dissolved in liquefied carbon dioxide, in place of methyl bromide the use of which is globally regulated as ozone depleting substance or a fumigant using methyl iodide dissolved in liquefied carbon dioxide in combination with one or more compounds selected from the group consisting of sulfuryl fluoride, methyl isothiocyanate, phosphine, ethylene oxide, carbonyl sulfide and propylene oxide, and a fumigation method for killing wood parasitic nematodes by using said fumigant.

1 . A fumigant for wood parasitic nematodes, comprising methyl iodide and liquefied carbon dioxide in which methyl iodide is dissolved. 
   
   
       2 . The fumigant for wood parasitic nematodes claimed in  claim 1 , wherein the concentration of methyl iodide in the liquefied carbon dioxide is within a range of 20 to 90 mass %. 
   
   
       3 . A method for fumigating wood, comprising killing wood parasitic nematodes by using methyl iodide dissolved in liquefied carbon dioxide in combination with one or more compounds selected from the group consisting of sulfuryl fluoride, methyl isothiocyanate, phosphine, ethylene oxide, carbonyl sulfide and propylene oxide.
